Logo wanted for martial arts club

We require a logo for our Taekwondo club, we've got some thoughts and other logos we like parts of.

Stevenage Taekwondo Club

The following are in no particular order (except possibly the first one has potential with the caveats listed), but each may give ideas.

Champion's Taekwondo - I like the fact that it's got a flag in the yin-yang, we could also use a sam-taegeuk.  I like the clean modern font, I like the silhouette overlayed kicker idea (but not doing that kick) I don't like the breakout electric text at the bottom.

Sport-Art Taekwondo - clean and simple, I like the use of oriental script at the bottom (it's actually Chinese whereas Taekwondo normally uses Korean script, but for now that doesn't matter)

Israel Taekwondo Federation - I love the kicker in the blue body protector - it's a great kick and anatomically accurate.

Chung-do-kwan - this is a very traditional logo that some people at the club like.  The fist image is very traditional, although we'd prefer English at the top to Korean as the club is taught/based in England.

Chang-moo-kwan - as our instructor got his black belt from the Chang-moo-kwan it may be nice if we had a concept that had a nod to the Changmookwan.  As an idea, the rearing lions could be replaced with rearing stags/dears as we're based in Hertfordshire, UK which has a stag (actually a Hert) as it's logo.

USA Taekwondo Centers - I like the way the flag and kicker comes out of it's traditional bounding circle.

If you're going to use a Yin-yang, please make sure that red is on top (as it is on the Korean flag).  If you're going to use a sam-taegeuk please keep the yellow on top and make sure the red is red.  I quite like the idea of the sam-taegeuk in the logo.

If you're going to use a flag it should be the Union Jack (technically the Union Flag).

- A clean logo
- Something not ultra modern (unless you think you have a really cool modern idea)
- Logo in unflattened vector format (Adobe Illustrator)

- Awful kicking images
- Taekwondo mis-written as Tae Kwon Do or Taekwon-do
